October 4, 2016 at 03:31 AM · I have a friend who recently purchased one of the diamond carbon fiber bows brand new and it was full of rosin so much so that he hasn't had to rosin since he got it and he has a $5,000.00 violin that has been covered in that rosin and the company that sold it to him is a trusted store here in Texas. I told him that he could possibly use a soft bristled tooth brush to remove some of the rosin will this harm the horse hair because I have been doing this too? But I can't believe that they sold him a $700-800 dollar bow with this much rosin in it you could practically rosin 3 or 4 new bows with the rosin that is on it.

If that's not an option for your friend, I did experiment cleaning bow hair with isopropyl alcohol. It turned out bad, and stuck few strands of hair together due to half-solved rosin. I ended up cleaning the hair with water, and brushed it until it dried. It's serviceable, but I won't do that again.
